Specification of Letters Patent.

Patented May 1, 1917.

Application filed Februafy 19,1915. Serial No. 9,404.

Be it known that I, AXEL F. ELrs'rRUM, a citizen of the United States, residing at Willmar, in the county of Kandiyohi and State of Minnesota, have invented new and useful Improvementsin Boosting-Poles, of which the following is a specification.

This invention relates to an improved perch or roosting pole for fowls, the object being to produce a device whereby the fowls may be kept free from lice and other ver min.

The object of the invention" is to produce a simple and improved perch having a recess in which insecticide may be placed, the construction being such that when the perch is warmed by fowls roosting thereon, the msecticide will evaporate, the fumes tending to detach and destroy the vermin.

A further object of the invention is to simplify and improve the construction of the perch or pole with a view to forming a simple and eflicient insecticide receptacle.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts whlch will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modificaresorted to when desired.

In the drawing,-

Figure 1 is a longitudinal sectional view showing a simple and preferred form of the invention.

Fig. 2 is a transverse sectional view of the same.

Fig. 3 is a transverse sectional view showing the invention applied to a bed slat.

Fig. 4c is a view partly in perspective and partly in section showing the invention applied to a nest protector.

Corresponding parts in the several figures are denoted by like characters of reference.

In the form of the invention shown in Figs. 1 and 2, the pole 15 is provided in its upper face with a longitudinal angular recess 16, the side walls of which, 17, are substantially at right angles to each other. The

ends of the recess or channel 16 are obstructed by end pieces 18. 19 is a cover member consisting of a strip of triangular cross section, the .widest portion of which is of a width equal to the widest portion of the channel 16. The side walls 20 of the strip 19 are disposed at an obtuse angle with respect to each other. the result being that the strip when placed in position will not completely fill the channel 16, but will leave an intervening space of considerable area in which insecticide may be placed. The strip 19, however, should extend the full length between the end members 18 so as to form a complete cover for the channel 16. The strip 19 is pierced by a number of vertical apertures 21, and several pegs 22 driven in the bottom of the channel 16 extend upwardly into some of said apertures to maintain the cover strip in position and to prevent its being tilted by the fowls when roosting on the pole. It will also be seen that the top face of the cover member is flush with the top of the pole, thus enabling the latter to be grasped by the feet of the fowls and this construction also tending to prevent displacement of the cover member.

In the operation of this device the insecticide is placed in the channel, and the cover strip is then placed in position. The upright pegs 22 projecting into some of the holes or apertures 21 will prevent any possibility of the cover being tilted out of position by fowls roosting on the perch. On the other hand, the placing of the cover in position causes it to dip into the insecticide and to force the latter upwardly between the inclined side walls 17 and 20 so as to completely fill the space between the bottom of the channel and the cover strip. When the pole becomes warmed by fowls roosting thereon the fumes 0f the insecticide will cause the vermin to leave the fowls, enabling the latter to rest quietly, thereby promoting health, sanitation and egg producing capacity.

The invention, besides being applicable to roosting poles for fowls, may be applied to bed slats for the purpose of exterminating vermin. In Fig. 3 has been shown a bed slat provided with an angular recess 61 identical with the recess 16 in Figs. 1 and 2, the channel thus formed being obstructed at the ends by end members 62. A cover strip ployed, the same being provided with apertures 64:, some of which are adapted to receive pegs 65 extending upwardly from the bottom of the.ohannel.

In Fig. 4; has been illustrated a nest protector consisting of a polygonal ring 70, the top face of which is provided with a channel 71 of angular cross section, a cover member 7 2 of triangular cross section being pro vided, said cover member having apertures 73 into some of which project pegs '74 rising from the bottom of the channel. The operation of this and other modifications will be readily understood.

Having thus described the invention, what is claimed as new, is:-

In a device of the class described, a member having a channel of angular cross sec tion, the side walls of such channel being substantially at right angles with relation to the channel and the side walls of the cover member, the latter being provided with apertures and the channel being provided with pegs rising from the bottom thereof into said apertures to prevent tilting and displacement of the cover member.

In testimony whereof I aflix my signature in presence of two Witnesses.
